1076 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1078 * device/lib/printf_large.c: removed inline assembly for portability and
1079 readability. Use printf_fast if speed or size are more important.
1080 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1081 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1083 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1085 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1086 prevent compiler warning
1088 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1090 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1091 moved to level 0 and declared as static. Also they are explicit
1092 placed in access bank. This was necessery because some times they
1093 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1094 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1095 optimizations. Currently only compare to unsigned char is implemented,
1096 * src/pic16/gen.c: added fReturnIdx array,
1097 * (struct resolvedIfx) is moved to gen.h and made public,
1098 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1099 * (aopForSym): added an optimization to directly store in stack of
1100 the operand of a SEND iCode,
1101 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1102 but as registers instead (AOP_REG) using the fReturnIdx array,
1103 * (pic16_freeAsmop): remove the freed register from the
1104 _G.sregsAlloc field,
1105 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1106 a compare of 'WREG',
1107 * (pic16_popGetTempRegCond): changed function prototype, now
1108 function takes also a bitVector argument v which holds the current
1109 set of registers that are allocated for stack access by aopForSym,
1110 registers allocated in aopForSym for accessing stack symbols are not
1111 any more part of the functions usedRegs field,
1112 * (genCall): some times aopOp is called for a stack variable to be
1113 send, aopForSym might perform the push, if this is true make sure
1114 that genCall doesn't push the variable twice by testing _G.resDirect,
1115 * (genFunction): changed testing for unspecified interrupt number
1116 from 256 to INTNO_UNSPEC,
1117 * modified selection scheme of frame pointer generation. Previously
1118 if function did use local registers a frame pointer was generated,
1119 now a frame pointer is generated only if function has arguments
1120 (that need PLUSW2 register access), or has stack arguments, or the
1121 compiler is not instructed to omit the frame pointer,
1122 * (genEndFunction): before restoring local registers that were saved
1123 in the function preamble, also restore the registers that *might*
1124 have been allocated for stack access,
1125 * (genRet): removed some old comments,
1126 * (genCmp, the active (RN's) version): added a call to the
1127 pic16_genCmp_special function to perform the compare with a more
1128 robust and optimized way,
1129 * (genInline): a feature has been added in inline code generation,
1130 which allows a wildcard variable substitution when writing inline
1131 assembly. Code is incomplete and experimental therefore undocumented,
1132 * (genCast): changed order of aopOp for result and right to allow
1133 aopForSym to directly load the result if possible,
1134 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1135 perform an optimized compare on some selected special occasions,
1136 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1137 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1138 generate an IVT any more,
1139 * src/pic16/main.c (pic16_optionsTable): added command line option
1141 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1142 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1144 * src/pic16/NOTES: Raphael Neider added in list of active developers
1145 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1146 jumptable_end to prevent bug #,
1147 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1148 inCond and outCond fields,
1149 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1150 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1151 turn off register spilling,
1152 * (packRegsForOneUse): synced with other ports' versions although it
1153 is not used currently,
1154 * (pic16_packRegisters): added an optimization while reading
1155 structure bitfields, some registers may be saved (malloc code is
1156 decreased by 80 bytes)
1158 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1160 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1161 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1162 this can be optimized more?
1164 2005-03-10 Raphael Neider <rneider AT web.de>
1166 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1167 genNearPointerGet): (hopefully) fixed access to bitfields via
1168 pointers (p->bitN = x; and x = p->bitN; failed)

1800 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1802 Adding support for replacing ljmps with sjmps in jumptables
1803 generated for switch statements. For now you need to set the
1804 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1805 Now 4 algorithms for mcs51 jumptable generation are used:
1806 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1807 addresses loaded pc-relative for up to 112 cases and stack-pushing
1808 target addresses loaded with offset from dptr for up to 256 cases.

1838 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1840 * added libc directory. The current version of LibC contains string
1841 functions, ctype functions and macros and some functions of the
1842 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1843 be extensively tested in the future. Standard disclaimer here.
1844 Library is not automatically build yet. But one can build it by
1845 invoking 'make' inside the libc directory.
1846 * added ADC library under libio. Preliminary version yet.

1855 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1856 * (pic16_storeForReturn): optimized return of 0,
1857 * (genCmp): experimental code for new genCmp which uses PIC18's
1858 special compare&skip instructions. Initial tests fail some times
1859 with variables grater than 1 byte in size, so new code is disabled,
1860 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1862 * (genCast): began a fix to optimize the casting of a bit to another
1863 bit, now assigning a bitfield to another bitfield will fail, sorry,
1864 * src/pic16/main.c: disabled the use of lr-support feature,
1865 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1868 bits with offset (case PO_GPR_BIT),
1869 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1871 * (isBankInstruction): modified to return 0 for no banking instruction,
1872 and 1 for banking instruction,
1873 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1874 caused stop processing pCodes after a inline assembly block,
1875 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1876 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1877 registers when it shouldn't,
1878 * src/pic16/ralloc.c (allocReg): add preliminary support for
1879 supporting a limited set of temporary registers,
1881 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1883 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1884 genDataPointerSet): ensure assignments always copy in MSB to LSB
1886 (loadRegFromAop): recognize CLRH optimization,
1887 (genFunction): optimize RECEIVE iCodes in reentrant functions
1889 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1891 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1892 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4886 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4888 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4889 loaded with the linker search paths (-L arguments) and the libraries
4890 to be linked with the current source (-l arguments). Changes
4891 currently will affect only the pic16 port.
4892 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4893 include path the port specific paths and port specific libraries,
4894 * gplink command now contains the $3 argument,
4895 * src/pic16/device.h,
4896 * src/pic16/device.c,: structure PIC_device is made public and
4897 renamed to PIC16_device, the same for variable Pics which is renamed
4898 to Pics16. Updated all references to them.
4899 * src/pic16/glue.c (pic16glue): corrected bug with code
4900 initialization which bypassed the variable initializations block.

4910 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4912 Documenting changes from previous commits.
4913 * configure.in (version 1.56),
4914 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4915 when generating output files to configure the pic16 library,
4916 but now I've commented it out, since gputils aren't installed in the
4917 SF compile farm, so library won't compile
4919 * device/lib/Makefile.in (version 1.56): initially I've added in
4920 target 'all' the prerequestive 'model-pic16' so it compiled the
4921 pic16 library, but now I've commented it out for the same reasons
4923 * added targets 'model-pic16' and 'objects-pic16' to compile the
4925 * added target 'port-specific-objects-pic16' to handle the
4926 generated libraries and copy them into the build/ directory
4927 * added target 'clean-intermediate-pic16' to clean intermediate
4928 files into pic16 directory
4929 * in target 'installdirs' added line to create directory pic16 in
4930 the installation path
4932 * device/include/Makefile.in (version 1.11): in target 'install'
4933 added lines to copy all header files to installation path,
4934 * in target 'installdirs' added line create directory for pic16
4935 headers in the installation path

4950 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4951 option so that it actually works. Made it specific to the z80, since
4952 the gbz80 doesn't have these kinds of I/O ports.
4954 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4956 * device/include/z180.h,

4969 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4971 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4972 changed interrupt vector table generation to only emit declared vectors.
4973 * device/include/Makefile.in: added missing backslash
4974 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4976 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4978 Mainly changes to support compilation of the device libraries
4979 * src/pic16/device.c: stack is allocated via symbol and not
4980 via literal number. The symbol is placed in the corresponding
4981 position of the data ram
4982 * (pic16_dump_section): relocatable and absolute uninitialized
4983 data are now emitted in sorted order to reduce section naming,
4984 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4985 weren't marked as being in the access bank,
4987 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4989 Added portion of GNU PIC Library under the directory
4990 device/include/pic16 and device/lib/pic16. These files
4991 contain the declarations of SFRs for the PIC18Fxx2 devices.
4992 The directory is initialized via configure from toplevel.
4994 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4996 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4997 the spilllocations to be compared correctly
4999 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5001 * src/SDCCast.c (decorateType): fixed bug introduced today
5003 2004-01-12 Borut Razem <borut.razem AT siol.net>
5005 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5021 * doc/sdccman.lyx: Moved and added some sections, small changes
5022 all over. Telling LaTeX to be less strict with word spacing
5023 to better keep the right margin. Changed some notes about
5024 maintainance of the ports in section 3.2.1 - is it OK like this?
5026 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5028 SDCC source changes:
5029 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5062 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5063 UPPER for immediate operands,
5064 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5066 * src/pic16/peeph.def: all peepholes with movff are commented out,
5067 because there is a problem in the pcode peep optimizer,
5068 * src/pic16/ralloc.c: the register allocator can now reuse local
5069 function symbols for another function. This saves register usage.
5070 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5072 Added file src/pic16/NOTES with information about program writing on
5073 the current port version.

5082 * src/SDCCmain.c : fixed #872250: -l command line defined library
5083 files are scanned before standard library files
5085 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5102 gen51Code): more efficient parameter receive for --model-large
5105 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5108 * src/z80/main.c: added missed needLinkerScript flags (more than
5109 one port structure defined in these file)
5110 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
5113 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

5126 needLinkerScript flag
5128 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5129 * src/pic/glue.c: added variable udata_section_name to
5130 override default uninitialized data segment definition for
5131 devices only with SHAREBANK memory (reported from Erik Epetrich)
5132 * (pic14emitOverlay): modified to emit a commented overlay segment
5133 directive when no overlay data exist
5134 * (picglue): modified to emit uninitialized data segment
5135 according to udata_section_name

5141 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5142 object file from '.rel' to '.o' in port->linker structure,
5143 changed size of fptr from 2 to 3 in port structure
5145 2004-01-07 Borut Razem <borut.razem AT siol.net>
5147 * support/scripts/sdcc.nsi: update PATH
5148 * support/scripts/sdcc.ico: craeted
5150 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5152 * device/include/Makefile.in: fix install
5153 * doc/Makefile: fix install
5155 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5157 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5159 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
5160 how the function variable allocation summary is displayed; also
5161 include information about variables allocated to the overlay
5164 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5166 * as/mcs51/lkmain.c: Help about -Y option

5176 LEFT_OP (left shift)
5178 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5180 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5181 (default behaviour).
5183 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5185 A python script to validate compiler diagnostic messages. It can be
5186 used to verify that sdcc complains about bad c source code and
5187 gives a good location of the error.
5188 * support/valdiag/Makefile,
5189 * support/valdiag/valdiag.py,
5190 * support/valdiag/tests/*
5192 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5194 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5195 * src/SDCCsymt.c (newEnumType),

5203 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5205 * src/common.h: added ifndef/define/endif macros
5206 around the header file.
5207 Bug reported from Jesus Calvino-Fraga
5209 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5211 * sdcc.spec: updated
5212 * device/include/Makefile.in: don't install CVS directories
5213 * device/lib/Makefile.in: added removal of CVS directories after install
5214 * doc/Makefile: fixed install, added local_icons
5215 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5216 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5217 * src/ds390/gen.c (genRightShift): fixed bug #870788
5218 * src/SDCCast.c (decorateType): fixed bug #870781
5220 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5222 PIC16 port related changes:
5223 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5224 added variable stackPos,
5226 * gen.c: genCall, assignResultValue: added support for
5227 pushing/retrieving function parameters to/from stack,
5228 genFunction,genEndFunction: setup stack frame for the
5230 genAddrOf: will be changed according to bug 863624
5232 * added files genutils.c and genutils.h which contain gen*
5233 debugged and optimised functions extracted from gen.c
5235 * glue.c: added variable 'externs' which holds extern symbols,
5236 pic16emitRegularMap: is modified to properly handle relocatable
5237 symbols under the new scheme,
5238 pic16createInterruptVect: is modified
5239 pic16printPublics: is modified to emit 'global' assembler directives,
5240 added pic16_printExterns to print extern symbols,
5241 pic16glue: initializes stack/frame pointer in the beginning of
5242 the assembly output. Temporary hack, will be corrected later,
5243 because gplink yet does not support stack and SDCC does not
5244 yet support a type of crt0.o object to create the final binary.
5246 * Removed many lines that contain 8051 legacy code.
5247 * The code is finally placed under a 'code' directive.
5248 * Added port specific options.
5250 * _process_pragma: simplified since now we do not need *special*
5251 include file to define SFR registers. But a separate header
5252 will be needed. This will be developed later.
5253 * _pic16_parseOptions: added, parses port specific options:
5254 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5255 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5256 --preplace-udata-with=
5258 * _pic16_setDefaultOptions: modified to initialize section names,
5259 but hack is temporarly out of order since it needs improvement.
5260 * _pic16_genAssemblerPreamble: configuration words are emitted by
5261 their address instead of their name. This part is incomplete and
5262 supports only the 18Fxx2 devices. Other devices will emit an error
5263 during assembly since they do not contain the same set of config
5265 * _pic16_genIVT: is modified,
5267 * pcode.c: added definitions for some hardware registers that are needed
5269 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5270 All PCI entries are updated. Now LFSR is supported.
5271 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5272 * added pic16_newpCodeOpLit2 to support instructions with
5273 two literal arguments
5274 * pic16_pCode2str: corrected code that emits assembler instructions
5275 with two literal operands and those that have an access bit modifier
5276 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5277 this fixes a bug which caused some labels to be lost, when an
5278 assembler directive was added, i.e. banksel,
5279 * pic16_FixRegisterBanking: improved logic that causes the insertion
5281 * InlineFunction: functions that are called once, are not any more
5282 inlined. This can be a port option in the future,
5284 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5286 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5287 hold the corresponding uninitialized symbols,
5288 * pic16_allocProcessorRegister: registers have explicit marked the
5290 * pic16_allocInternalRegister: registers are explicit marked as
5292 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5293 processing list, so bit registers were lost,
5296 * ralloc.h: added field 'accessBank' and original symbol operand
5297 in register definition,
5298 * removed the field isMapped from register definition,
5300 ** Several functions have been removed from various sources:
5301 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5302 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5303 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5304 pic16_assignRelocatableRegisters
5306 ** others have been introduced:
5307 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5308 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5310 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5312 * support/scripts/inc2h.pl: changed definition of BIT_AT
5313 to emit 'sbit at' instead of 'bit at'. This was a request.
5315 PIC16 port related preliminary changes:
5316 * gen.c: prefixed function popRegFromString with
5317 pic16_ and all references to it corrected
5318 * pcode.c: all pic16_pc_* hardware registers prefixed
5319 with underscore (_),
5320 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5321 * ralloc.c: newReg(): when register is REG_SFR then
5322 set address to rIdx,
5323 pic16_allocProcessorRegister(): marks register wasUsed=0
5324 pic16_writeUsedRegs(): added a call to assign processor
5325 registers via pic16_assignFixedRegisters
5327 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5329 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5330 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5331 variables in unused register banks. Also the SSEG is placed
5332 wherever there is enough space for it, and IDATA can be anywhere
5333 in internal RAM. For now compile using -Wl-Y[stack_size].
5334 The mem file is different for this option as well, since it
5335 makes no sense of talking about DSEG lenght.
5337 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5339 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5340 in certain cases, e.g. when ROM assignment, patch provided
5341 from Albert den Haan.
5343 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
5345 Many signedness and type propagation fixes:
5346 * src/SDCCicode.c: made geniCodeCast() static
5347 replaced SPEC_ by IS_ (cosmetic)
5348 (operandOperation): fixed div and mod operation
5349 (usualBinaryConversions): added support for promotion of char
5350 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)

6346 fetching of the pointer
6347 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6348 copied from genNearPointerSet()
6349 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6350 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6351 If they pop r0/r1 they must be called in the opposite order than aopOp().
6352 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6353 (resp. --stack-auto), prepared for --xstack

6362 these ports have their own __sdcc_external_start()
6364 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6366 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6367 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6368 type for bits was changed. It resulted in bit variables becoming
6369 global, which is not permitted in PIC 14 assembly output.
6371 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6373 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6375 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6377 Z80 and MCS51 linkers complaint if a public symbol is defined

6386 A few small changes that speed up the peephole optimizer.
6390 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6392 Try to make the peephole optimizer smarter by maintaining
6393 an association between the assembly source code and the
6394 iCodes that originated them. Put this information to use
6395 with a new peephole rule condition "notVolatile" so that
6396 the rules can be aggressive yet still safe.
6401 * src/mcs51/peeph.def
6403 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6407 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6408 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6409 if the left or right operand symbols have the accuse flag set.
6411 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6413 Changed the type of the result of the ! (NOT) operator to char;
6414 previously it returned the same type as the source. This allows
6415 us to eliminate all the genFloatNot functions (all of its target
6416 implementations were very buggy) since !float can use the same
6419 * src/SDCCicode.c (ast2iCode): ! returns char
6420 * src/mcs51/gen.c (genNot, genNotFloat),
6421 * src/ds390/gen.c (genNot, genNotFloat),
6422 * src/z80/gen.c (genNot, genNotFloat),
6423 * src/pic/gen.c (genNot, genNotFloat),
6424 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6428 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6429 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6430 during interrupts. Ensure WSAVE is located at a shared bank address.
6431 2. Fixed page selection in some places
6432 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6433 the registers name strings.
6434 4. Fixed "signed / unsigned compare" compiler warnings.
6435 5. The PIC port manages its own allocation of the general purpose
6436 registers, but makes no attempt to reuse them. As a result when
6437 compiling it soon runs out of general purpose registers. Some
6438 additional code was added to the files pcode.c and device.c to walk
6439 through the function call tree and rename the registers so that they
6449 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6450 genPlus() & genMinus() when the result is the same as left or right

6456 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6458 Made bitfield a distinct type from bit so that bitfields
6459 convert as per ANSI C and bits retain their traditional
6460 boolean style behaviour. Implemented bitfield support in
6468 * src/ds390/gen.c: bit v bitfield split
6469 * src/z80/gen.c: New support for bitfields
6470 * support/regression/tests/bitfields.c: reenabled z80,
6473 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6475 Rules 246.x, 247.x relate to bitfields, the others speed up
6476 access to xdata mapped I/O devices.
6478 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6480 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6482 Cleaned up genPackBits and genUnpackBits and added two helper
6483 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6484 for literal assignments in genPackBits (thanks to Frieder for
6490 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6492 Fixed bug #748310 (pointer to function type mishandled when the
6493 function name is omitted). Also fixed a SIGSEGV when a function
6494 attribute (reentrant, etc) is used on a non-function or on a
6495 function but misplaced before the parameter list.
6497 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6499 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6522 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6524 Made the constant following the "interrupt" keyword optional. If
6525 omitted, the function will not automatically be given an entry
6526 in the interrupt vector table (similar to #pragma NOIV, but
6527 less syntacticly kludgy). The interrupt number is also now
6528 range checked. Also fixed a bug in the high order bit example

6542 * src/SDCCicode.c (operandOperation): rewritten some ops
6543 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6544 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6546 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6547 be re-activated by defining REDUCE_LITERALS)
6548 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6549 unsigned, but are signed by default
6550 * src/SDCCval.c (constVal): rearranged
6551 * src/SDCCval.c (valMod): preliminary fix
6552 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7004 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7005 the regression tests I'm not brave enough to enable 245.b, 245.c
7006 * doc/sdccman.lyx: added latex preamble for hyperref package.
7007 Using pdflatex this will give you a hyperlinked pdf file with
7008 bookmarks. (prepend '%' before /usepackage if this breaks something)

7046 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7048 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7049 it can be defined with CFLAGS when running configure
7050 * src/SDCCmain.c: fixed compiling + linking with object files
7052 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7055 added --disable-pic16-port
7056 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7057 * src/SDCCmain.c: linkOptions is changed to set *,
7058 added if/endif conditional macros to remove options help
7059 messages from optionsTable when a port is not configured, added
7060 support for the PIc16 port in the ports table, when executing
7061 the compiler with no port specified on command line, a default
7062 port is selected with the new macro DEFAULT_PORT which is
7063 defined in port.h, in setDefaultOptions() linkOptions is removed
7064 from initialization assignment, since now it is a set,
7065 parseCmdLine uses setParseWithComma for linkOptions, in
7066 linkEdit() linkOptions are accessed with new function indexSet()
7067 which returns the i'th item of a set variable. See SDCCset.c, in
7068 linkEdit() when calling buildCmdLine(), added linkOptions as
7069 last argument. Now users can pass arguments to gplink via the
7070 -Wl option, main() uses pic16glue() to glue up pic16 programs

7082 * src/pic16/glue.c: commented out some error producing lines
7083 * src/pic16/main.c: __config directives are commented out to stop
7084 gpasm complaining and test the linkage with gplink, _linkCmd and
7085 _asmCmd changed to be more gplink and gpasm friendly
7086 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7087 produced an error when parsed, peep rule 12 is added to utilize
7088 movff, but it is commented out since the pCode does not support
7089 yet a command with 2 address arguments
7091 2003-05-18 <johan AT balder>
7093 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7094 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7118 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7120 2003-05-11 Borut Razem <borut.razem AT siol.net>
7122 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7123 the path of bin directory, so that PATH is the only env. variable, which has to be set
7124 in case of standard installation.
7125 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8154 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8156 * in \sdcc\as\mcs51\ changed these files in order to create an
8157 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8158 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8159 following files to include the previous two files: aslink.dsp,
8160 Makefile.aslink, Makefile.bcc, and Makefile.in.
8162 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8163 .adb instead of .cdb
8165 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8167 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8168 value from option --iram-size.
8170 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8172 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8175 2002-09-18 <wiml AT hhhh.org>
8177 * SDCClrange.h: exposed setFromRange() and setToRange()
8178 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8179 packRegsForAccUse() (bug 542397)
8180 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8181 multiple times and emitting the fetch operations more than once
8182 added aopGetUsesAcc() function to allow binary operators to
8183 fetch their operands in the correct order; made genMinus() emit
8184 compact code for X = LITERAL - Y
8186 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8187 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8188 sprintf() in line 1267.
8190 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8191 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8194 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8195 Changes to aslink (All the changes are marked with 'JCF'):
8197 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8200 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8201 area BSEG. Also moves, if possible, the DATA area down into the internal
8202 ram so more space is available.
8204 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8207 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8208 not bytes. Function summary() which creates a memory usage summary
8209 file with extension .mem. Reports of overlaping stack and small stack
8210 size. If the space for the stack is less than 16 bytes aslink trows a
8213 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8214 the 8051. Option 'y' for memory summary output file.
8216 Changes to sdcc (All the changes are marked with 'JCF'):
8218 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8220 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8221 overlaying area for it (uses RegBankUsed[4]).
8223 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8224 bank zero as used by default. By default aslink locates the stack
8225 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8226 the creation of the .mem file. Delegates the allocation of data area
8227 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8228 the begining of the stack area to aslink.
8230 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8231 glue() in SDCCglue.c creates an area for it.
8233 2002-09-03 Borut Razem <borut.razem AT siol.net>
8234 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8235 sdcc/src/pic/glue.c:
8236 introduced atexit() handler for teporay files removal in case of
8237 errors, assertions, ...
8239 2002-08-29 Borut Razem <borut.razem AT siol.net>
8240 * sdcc/support/cpp2/auto-host_vc_in.h:
8241 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8242 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8243 Maybe there is a similar problem with BORLANDC? It should be checked!
8245 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8246 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8247 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8248 was not executed, and the compiler (cl) launched a warning:
8249 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8251 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8252 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8254 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

8261 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8262 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8263 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8264 - added Release configuration in VS projects
8265 - review of compiler an linker options
8266 - VC .exe files are generated in bin_vc directory, not to interfere
8267 with binaries generated from other projects (cygwin, mingw, bcc ...)
8269 * sdcc/src/yacc.dsp: added
8271 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8272 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8273 and insert the version number definitions from .version
8275 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8277 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8281 removed from CVS, generated automatically
8283 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8284 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8286 2002-08-11 Borut Razem <borut.razem AT siol.net>
8287 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8289 2002-08-10 Borut Razem <borut.razem AT siol.net>
8290 * src/SDCCmain.c (main):
8291 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8292 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8293 The consequence was that some temporary files were not removed.
8296 unification of code in functions tempfilename() and tempfile():
8297 function tempnam() is defined in Visual Studio 6.0 and .NET
8299 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8301 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8302 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8303 - removed compiler command line option /WX: Treats all warnings as errors
8304 - update a list of source files, included into the project
8306 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8307 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8308 changed project type to Generic Project so that can be correcly converted to VS.NET project
8310 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8312 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8314 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8316 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8317 added return 0 statements after assert() to make compiler happy
8319 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8320 added newline in the def file to keep MSC compiler satisfied
8322 * sdcc/src/z80/gen.c:
8323 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8324 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8325 - solved MSC error in function aopDump()
8327 * sdcc_vc.h: define PREFIX as "\\sdcc"
8329 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8381 Initialized the new field char *Processor field to NULL in all ports
8384 Compiler generated registers for interrupt context saving
8385 were not getting allocated.
8387 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8390 Fixed left shift. Will promote the left side of a left shift
8391 if a) left shifting more than size of operand or b) when assigned
8392 to something size > size of left side
8394 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8502 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8504 * sdcc/src/SDCCloop.c:
8505 Previous fix was not good. basic blocks that have "break" or "return" are
8506 not really partof a loop , but live ranges used in these blocks should
8507 be live thru the entire loop, so set partOfLoop but don't add them to
8510 2002-02-21 <johan AT FRIJA>
8512 * src/SDCCcse.c: fixed bug #514308
8514 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8539 Karl and Johan start ucsim XA support. Most dissassembly working,
8540 about 75% emulation done(plenty of work remaining).
8542 * sim/ucsim/z80.src:
8543 Add Z80 support to ucsim, add test-ucz80 regression test,
8544 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
